Yes, changing jvm.config will affect all instances by default. I
recommend that you configure the specific instance in question to use

The difficult part of my job is that I administer the ColdFusion server, but
I am not allowed direct access to the server.
Yeah, those sort of setups suck because you can't just get in and do
what you need to.

Questions like that hard to answer generically.
In general, you need to add some GC args to take a look at your garbage
collections and how often they are running as well as how much memory
you generally use. (jConsole will also be a good step) Chances are, if
your server has enough RAM and
Did anything change with the configuration of the server on January 5?

Most of the time I've found that problems like this are related to
either a large data query that is hanging or timing out, and not
notifying the Coldfusion server. Or a program that has an infinite
loop

An advice on what it takes to set up jConsole?
What are my options here? Is there an easier way to get to this thread
information?
JConsole is _not_ necessary to get a thread dump of your JVM. All you
need for that is the snapshot tab in ColdFusion's built-in server
monitor.
JConsole will help you track your memory usage.

Very useful tool! and can be setup so you can access the server remotely -
it doesn't have to run on the same server.

In that case, I would focus in on getting some stack traces of exactly
